Whole interview comes off much less incendiary than the two quotes that the OP presents. I don't know why people make such a big deal. Ritz finished 8th, within a minute of previous winners Meb & Marlison Gomes dos Santos. To me that is a very good performance. He didn't win it this time but maybe with some tweaks he can do it next year.
Some of the commentary surrounding ritz has to be 'great white hope' syndrome, IMO. Sure, he should not have said some of the things he did before the race, but that's just human nature.
